Instantaneous and stored water heaters heat water where only a cold mains water supply is available (such as in a utility room or commercial environment). With an instant hot water heater, the heater powers up when water starts to flow through the unit (such as when a tap is opened) and uses no power when it is in standby operation. This allows these water heaters to provide a very economical solution for hot water on demand. Triton's water heaters have a range of kilowatt options and sizes available, an option to suit a variety of needs - including under-sink options from the Triton Instaflow range. Whether for a hand basin tap for heating water on demand for handwashing, 2 outlets or a kitchen tap, you'll find the ideal solution from our range of electric water heaters.
